The knowledge of car inverter

What is the inverter?  What's the use of the inverter? 

--------------------------------------------------------------------------------

The inverter is an electronic device which can convert low voltage (12V or 24V) DC into 220V AC. We usually rectify 220V AC into DC for use, but the use of the inverter is just on the contrary, so it is called "inverter". We are in a "mobile" time, mobile office, mobile communication and mobile recreation, we not only need the low voltage DC from batteries or storage batteries, but also need the indispensable 220V AC even more in our daily life, and the WELLSEE inverter can meet your needs of this.

The types of inverters classified by different output waveforms?
--------------------------------------------------------------------------------

Classified by different output waveforms,inverters can be classified into two types: the square wave inverter and the sine wave inverter. The square wave inverter outputs the poor-quality square wave alternating current with the positive maximum to negative maximum produced almost at the same time, so the current can cause severe uncertainty to the load and inverter itself. The sine wave inverter outputs the sine alternating current that is same with our electrical network for everyday use or even better, which can drive any sort of load, and it does not have the electromagnetic pollution in the electric network.

What is the meaning of "Inductive Load"?
--------------------------------------------------------------------------------

In a common expression, Inductive Load means the high-power electrical products which are produced with the application of electromagnetic induction principle, such as electric motors, compressors, relays, fluorescent lamps, and so on. Such products need to be started by the starting current which is much larger (about 3-7 times) than the maintaining current required in normal operation. For example, the starting power can be as high as 1,000 watts or above for a refrigerator which consumes about 150 watts of electricity in normal operation. In addition, the inductive load will produce counter electromotive force voltage at the moment of making or cutting the power, and the peak of this voltage is much higher than the voltage that an automotive inverter can bear, so it is very easy to cause the instantaneous overload of an automotive inverter so as to affect the service life of the inverter. Therefore, such electrical appliances have stricter demands on power supply waveforms.
